Current evaluation

The original version-access use case is already available through undocumented CRAFT_PROJECT_VERSION, but support for craftctl get/set version remains undecided and needs maintainer direction.

Suggested action: needs triage

Reason: Integration tests show ${CRAFT_PROJECT_VERSION} is populated during override execution, providing an undocumented workaround for reading the version, but no Rockcraft registration for craftctl get/set version was found. The latest comment explicitly asks whether the craftctl design remains wanted, while the issue has no labels or implementation commitment, so its read-versus-set scope and priority need triage.

Issue body

It would be useful to be able to grab the version of the ROCK being built as part of the various scripted sections in `rockcraft.yaml`. Something like: ```yaml version: "2.4.5" # ... parts: some-part: plugin: nil override-pull: | wget -O /tmp/product.tar.gz "https://releases.megacoolvendor.com/product/$(craftctl get version)_linux.tar.gz" ```

Recent triage notes CRAFT_PROJECT_VERSION env var already covers the use case; gap may be documentation. Awaiting maintainer confirmation on whether craftctl get version is still wanted.
